[outages] Charter issues this morning?

[Jeremy Charles]

Anyone else using Charter Internet have issues with connectivity this morning?

We (AS 10359) have site-to-site VPN tunnels to about 150 customers across the US.  We started seeing loss of connectivity to about 20% of them at about 06:25 CST.  When we filtered out all advertisements sent/received via Charter, we regained connectivity to everyone.  (We have two ISPs in addition to Charter.)

Additionally, our total aggregate Internet consumption jumped from about 200 Mbps to 500 Mbps as soon as Charter was taken out of the mix.  It looks like a lot of traffic was preferring to come to us via Charter (which is normal) but just wasn't making it here.

One of our engineers waited on hold for Charter for about 20 minutes and then gave up to go get coffee.   :-)
